Description

Technical Field

[0001] The present invention relates to the technical field of laser emitters, and in particular to a laser emitter structure. Background Art

[0002] Laser emitters are devices that can emit lasers, which can be divided into gas lasers, solid lasers, semiconductor lasers, dye lasers, etc. When producing and processing metal parts such as parts, laser cutting and other operations are required, and the corresponding laser emitter structure is required.

[0003] The existing Chinese patent application with publication number CN117346104A discloses a laser transmitter, laser equipment and visual equipment, including a prism holder, a laser light source arranged in sequence along the optical axis, a collimating lens and a Powell prism, the prism holder is provided with a mounting cavity for mounting the Powell prism, the incident end of the prism holder is provided with a first light hole connected to the mounting cavity, the emitting end of the prism holder is provided with a second light hole connected to the mounting cavity, the second light hole and the first light hole are both coaxial with the Powell prism; the invention, by providing the first light hole and the second light hole, allows the main light forming the laser line to pass through, plays a role in shielding stray light, thereby reducing the reflection of the surface light, which is beneficial to reducing stray light; it can also reduce the stray light reflected to the main light area.

[0004] However, the laser transmitter has the following defects when used:

[0005] 1. When an existing laser transmitter emits a laser for cutting and other operations, the laser light source emits a laser, and passes through multiple sets of lenses to refract and focus the emitted laser to achieve the laser emission operation. However, when multiple sets of lenses are in operation for a long time, dust and other impurities in the working environment will enter the interior of the instrument and adhere to the surface of the lens, affecting the effect of laser emission. At this time, the lenses installed in the laser transmitter need to be cleaned. The traditional method is to disassemble the laser transmitter structure to complete the lens cleaning operation. The operation is not convenient and it is easy to cause damage to multiple sets of lenses during the disassembly process;

[0006] 2. Existing laser transmitters usually consist of a laser medium and an energy source that can produce light amplification, where the energy source for light amplification is usually multiple sets of lenses.

[0051] Compared with the prior art, one or more of the above technical solutions have the following beneficial effects:

[0052] 1. In the laser transmitter structure, multiple sets of lenses are required for protection, calibration, and focusing when emitting the laser. At this time, the multiple sets of lenses (upper, middle, and lower refractive lenses, calibration lenses, and focusing lenses) for laser operation can be pulled out of the assembly shell respectively. It is more convenient to clean the lens surface later, and there is no need to open the assembly shell to clean the lenses, which can improve the efficiency of cleaning the laser lens surface. At the same time, for the focusing lens, a laser lens, it can be installed to the inside of the assembly shell through the lower supporting lens cover and the upper fixed lens cover set externally. At this time, the lower supporting lens cover and the upper fixed lens cover can protect the focusing lens set on the inside thereof on the one hand, ensuring that the surface of the focusing lens will not be damaged or worn during subsequent pulling or assembly. On the other hand, the space on the upper and lower sides of the focusing lens can be masked to prevent gaps, ensuring that there will be no light leakage when focusing the laser, and no damage to the eyes of the staff, thereby improving the safety of laser operation;

[0053] 2. In the laser transmitter structure, when the laser transmitter emits laser for cutting and other operations, the emitted laser can first pass through the upper refractive lens, and then be transmitted to the calibration lens and focusing lens set at the bottom for laser calibration and focusing operations. At this time, the upper refractive lens can refract the laser to ensure that the laser can be refracted to one side of the calibration lens and focusing lens for calibration and focusing operations. At the same time, with the upper lens cover set externally, the upper refractive lens set inside can be protected, reducing the probability of dust entering the upper lens cover and adhering to the surface of the upper refractive lens, thereby improving the effect of the laser during operation;

[0054] 3. In the laser transmitter structure, the upper protective shell, the middle metal shell, the focusing metal shell and the lower protective metal shell for assembling the upper refractive lens, the calibration lens, the focusing lens, the middle refractive lens and the lower refractive lens are all installed by threaded connection, ensuring that the upper protective shell and the middle metal shell, the focusing metal shell and the fastening metal lens cover as well as the lower protective metal shell and the fastening metal lens cover can be assembled and fixed together, which ensures the convenience of assembly on the one hand, and on the other hand, the upper refractive lens, the calibration lens, the focusing lens, the middle refractive lens and the lower refractive lens installed inside thereof are more stable and firm during actual operation, and will not cause problems such as displacement or shaking;

[0055] 4. In the laser transmitter structure, the lower supporting lens cover and the upper fixed lens cover are connected by a connecting rod structure arranged on the outside. On the one hand, it ensures the firmness of the connection and assembly between the lower supporting lens cover and the upper fixed lens cover, and does not cause a gap at the connection between the two during subsequent laser operations. On the other hand, when the focusing lens is disassembled for cleaning, the lower supporting lens cover and the upper fixed lens cover can be connected together, reducing the probability of damage to the focusing lens surface during subsequent assembly of the focusing lens.
